How do you maintain grape vines?

Can all grapes be spur pruned?
Grape vines should be either spur pruned or cane pruned, depending on the variety of grape.

What is the difference between spur pruning and cane pruning?
Spurs originate along the length of the cordon. With cane pruning, several buds are retained on one year old wood. Canes are longer and contain more buds than a spur. Typically several buds are retained per cane when cane pruning.
Should Concord grapes be spur or cane pruned?
